woon-WORKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 279,051, dated .Tune 5, 188e.

Application 'filed August 26, 1882. (No model.)

T o all whom it may concern.:

Be it known that we,\T1LLIAM E. VARNEY and NV. J. HULL, citizens of the United States, and residents, respectively, of Daytonville and Vellman, in the' coimty of Vashington and State of Iowa, have invented a new and valuable Improvement in Vood Working Machines, e nd we do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and tothe letters and iigures of reference marked thereon.

Figure l is a side elevation of a machine embodying our improvements. Fig. 2 is an end view, and Figs. 3 and et are detail views of parts of the clutch mechanism. Fig. 5 is a cross-sectional view. Fig. 6 isa detail view showing the curved slotted arm and its connections, and Figs. 7, 8, and 9 are detail views showing the mortising-table. Fig. l is a vertical cross-sectional view oi' that portion of the clutch mechanism shown in Figs. 3 and 4. y

This invention has relation to wood-working machines; and it consists in the construct-ion and novel arrangement of p arts, as will be hereinafter fully described, and particularly point.

ed out in the claims appended.

In the accompanying drawings, the letter A designates the bench or bed frame to which the adjustable mechanism is attached. The' benchy frame is of the ordinary construction, longitudinally slotted and anged to receive the adjustable parts before mentioned.

The ordinary treadle is employed to operate the mechanism but steam-power may be ap plied for this purpose.

A sliding frame is secured to the bench-frame in the usual manner, and havingV the usual screw-threaded shaft with the center-point for centering the piece to be operated upon, and a screw-clamp for locking the screw-shaft in position, the other end abutting against the ordinary chuck upon the main shaft D, having its bearings in standards rising from the benchframe, and provided with the usual oilicups.

E designates an auxiliary or upper mandrel, working in an eccentric sleeve, F, having bearings in the upper ends of arms G G,articulat ed upon collars H, projecting from the inner faces of the standards I, near their upper ends.

is provided with a washer and thumb-nut for securing the upper mandrel in any position' to which it may have been adjusted.

' The main mandrel D is provided at its outer end with a fri ction-wheel, K, having a grooved extension, K', for the reception of an endless band, and said friction-wheel K is secured by screws to the inner face of the' ily-wheel L. The outer end of the upper mandrel, E, is also provided with a friction-wheel, L', grooved for the reception of the same band, but smaller in diameter than the wheel K. The eccentric sleeve F is provided near one end with an adjusting-lever, M, by which the friction-wheels may be thrown in and out of gear. Vhen the friction-wheels are in gear, the upper mandrel, E, is revolved in a direction away from the operator. A band, M', connects the frictionwheels K and L', and when the said wheels are out of gear causes the upper mandrel to revolve toward the operator. lt willbe of course understood that both mandrels revolve in the same direction under the same adjustment. The main mandrel D is also provided between its bearings with a double pulley, N, the purpose of which `will be hereinafter explained. The outer face ofthe fly-wheel is provided near its center with a rim or collar, N, projecting in a direction parallel with its periphery. The outer end of the main shaft D, has a countersink to receive a center-point, and this end rests withinthe bore of the iiy-wheel L. A short shaft, N, pointed at both ends, has one of its bearings within the countersink of the main shaft D, the other bearing being in an arm, O, at the end of the bench or lathe-frame A, an adjusting-screw, O', being employed to compensate for the wear ofthe short shaft N. A collar, l), is secured to shaft N by a setscrew, and has au inwardly-projecting sleeve provided with a cross-arm, O, rounded at its ends, as shown. At the end O of said cross arm, and slightly to one side thereof, a screwpin, P, is inserted into the inner face of collar P and projects beyond the inner faceI of the cross-arm O".

An eccentric ring, Q, provided with projec- IOO scribed.

tions Q Q in diametrically-opposite positions, has upon the projection Q2 on its inner face a friction-j aw, R, adapted to embrace the collar or rim N when in place. The opposite projection Q is provided with a friction-block, Q, which at times bears upon. the outer face of the collar or rim N. the eccentric ring Q extends inwardly, as shown, and is provided with a radial slot, R', through which a screw, R, is passed into the collar P, directly opposite the screw-pin P, upon which screw R the eccentric ring gravitates when rotated, to cause the proper engagement of the friction-clutch. A screw, S, projects inwardly from the inner periphery of the eccentric ring Q at the middle point ofthe junction ofthe friction-jaw R, causing the engagement of the screw-pin P and the screw S after the friction-j aws have passed the lower end of a vertical central line while the machine is in operation.

Horizontal arms T T extend laterally in opposite directions from the base of the arm O, the arm T being provided at its outer end with a journal, T, upon which is an oscillating band-wheel, T, which is connected by a strap to the upper end of the spiral spring T, which is in turn connected at its lowerend to an arm, T5, projecting from the leg of the bench-frame, as shown. A band or belt, U, is connected by rivets to the periphery of the band-wheel T,

the other end of said band being connected to Y the short shaft N, so that when the spiral .spring T* is retracted after having been first extended the band U may be coiled upon the short shaft N"l by the action of the treadle and other A operating mechanism hereinafter de- The arm T is also provided at its outer end with a bea-ring, T, and in line with the same is a bearing, TT, at the end of an arm, T8, secured to bench-frame A, between the standards l.

projecting beyond said bearings for the reception of an oscillating band-wheel, NV, ofthe same size as the band-wheel T9, which is, however, set in nearer the ily-wheel a distance equal to the width of its rim. This bandwheel W is also provided with aband, V, one end of which is riveted to the rim thereof and the other end secured to the short shaft N2, so as to wind thereon when the band U uncoils therefrom during the operation of the ma- The inner end of the shaft V is provided with a smaller baudwheel, X. To this wheel X is connected a strap, X', one end of which is secured to the periphery thereof` by a rivet, the other end being detachably connected, by a clamp, X, or otherwise, to one end of a lever, X, the other end of which is permanently secured to the rectangular rock-shaft Xt journaled in the rear legs of the benchirame, near their bases, as shown. Atreadle, Y, is also connected to this rock-shaft.

Z designates the adjustable lathe-rest.

As the treadle rises the strap V is unwound The projection Q of The shaft V, having a collar, V, is journaled in the bearings Tt and TT, its ends from its colla-r on the shaft N2 by the action of the spring Ti, `and at the same time the strap W" is wound upon its collar on said shaft N2, and the clutch mechanism isv carried backward until a downward movement of the treadle causes it to engage the rim N and turn the fly-wheel and give it a continuous motion under a repetition of the manipulations of the treadle, the slot R permitting the rim N to pass while the clutch mechanism is moving backward under an ascending movement of the treadle, while the block Q engages it and imparts forward motion to the iiy-wheel when the treadle is descending. The back gear, Z, is preferably attached to the standards l I, in order that it maybe removed at the same time therewith.

Vhen the disk P, as shown in Fig. i, is moved contrary to the hands of a clock, the eccentric Q, deriving motion from the pin R,

Vwill clamp the rim N, and the further movement of the pin R2 will rotate the eccentric and wheel L. W'hen t-he disk P is moved in the reverse direction-i. e., in the same direction as the hands of a clock-the eccentric Q dis engages itself from the rim N and falls by gravity against pin P2, and is carried thereby to its original position.

a designates a table provided with vertical legs a', passing down through vertical sleeves flat opposite ends of a casting, a?, adapted to fit the lathe-frame, and attached thereto adj ust'- ably by a bolt and clamping-nut. This table a is provided about the middle of its length with the depending threaded rod ai, fixed thereto, which passes down through the sleevev a, rising from the center of the casting a, and provided with a hand-wheel, al, by means of which the table may be adjusted vertically.

The side ra-ils, d d, of a metallic frame, d?, are connected by end rails, d, and are beveled on their inner edges to fit the bevel-edges of the table a. The outer edges of the 'end rails, d, are beveled downwardly and inwardly to form guides for a sliding bed, e, having de pending studs `e eil on its lower face, against which the curved end of a lever, ve", pivoted in a bearing in the side rail d works to operate the sliding bed e forward and backward longitudinally of the lathe to feed material to the cutter'and withdraw it after it has been operated upon. The upper face of the bed e is of wood, to protect the cutters. Curved arms f j' rise from the bed e, the curve being toward the cutters, and are connected attheir upper ends by a cross-bar, j", near each end, in which work threaded cranks f, provided at their lower ends with a clamping-bar, j, by which the material vto be operated -upon is held in place on the bed e. The front side rail d, of the metallic frame di has a threaded depending lug, f5, about the middle of its length, for the reception of a screw-bolt, f, by which one end of an adjustable crank-arm, f7, is connected thereto. ,The other end of this crank-arm j" is connected by a headed bolt, f8, and nuts and IOO washers to a grooved arm, g, ou the upper shaft, g', of the back gear, Z, so that this end ofthe crank-arm may be adjusted by means of the headed bolt fB within the groove g of the arm g, to shorten and lengthen the stroke of the crank-arm f7, which operates the bed e back and forth laterally on the table a. By this means the length of the mortise to be formed by the rotary cutter may be regulated. Power is communicated to the back gear, Z', by means of a cored spiral wire belt, Z2, leading from the double' pulley N upon the main shaft D to a pulley upon the upper shaft, g, of the back gear, Z. lVhen the back gear is not used it is only necessary to throw off the wire belt Z2.

K designates the arm for carrying the jigsaw, secured by a bolt, K2, to the bench-frame A, but this forms the subject-matter of a separate application, and is not claimed herein. The free end of the arm K is provided with vertical ways K, in which a slotted slide, K4, works. The lower end ofthe slotted slide K* is provided with a downwardly and inwardly inclined lateral recess, L4, which is intersected at right angles by a vertical recess, the latter toreceive the upper end ofthe saw-blade.

N is a vertical bearing,V in which a rod, N, is vertically adjustable, and is provided at its lower end with an adjustable bifurcated foot,

N2 is a slot in the arm K; M, a stud in said slot, and M is a circular saw; but these elements are designed to form the subject of separate applications, and the right is hereby reserved to le the same.
